What should I do if I receive a suspicious trading call?

You don’t share any account details, OTP, PIN, or password with the caller, regardless of how confident or official they sound, since legitimate brokers and SEBI-registered advisers don’t ask for these over a phone call. You try to independently verify the caller’s identity by checking whether the person or entity is actually registered with SEBI, using SEBI’s official registered intermediary search, rather than trusting a name or credential the caller provides verbally. If the call involves a stock tip or investment recommendation, you treat unsolicited tips with real skepticism, since SEBI has repeatedly flagged fraudulent tip-and-pump schemes run through phone calls, messages, and social media as a major source of retail investor losses. You report suspicious calls to your broker’s official support channel and, if it involves a clear attempt at fraud or impersonation, to SEBI directly through the SCORES portal, rather than just hanging up and forgetting about it, since reporting helps flag repeat offenders.
